Cov Txheej Txheem Maleic Anhydride (MA) C4 Olefin zoo li cas?

Maleic Anhydride (MA) C4 Cov Txheej Txheem Olefin
Cov txheej txheem no siv cov khoom siv zoo (n-butene, butadiene) hauv cov feem sib xyaw C4 ua cov khoom siv raw, uas cuam tshuam nrog huab cua (lossis oxygen) ntawm cov pa roj oxidation hla V₂O₅-P₂O₅ catalyst los tsim maleic anhydride ma. Hauv qhov kev cuam tshuam, n-butene thawj zaug dehydrogenates rau butadiene, tom qab ntawd oxidizes rau maleic anhydride ma. Cov khoom lag luam suav nrog CO, CO₂, dej, me me ntawm acetaldehyde, acetic acid, acrolein, thiab furan.

Vim li cas ho xaiv Maleic Anhydride? Nws yog lub hauv paus ntawm cov polyester resins tsis muaj zog zoo tshaj plaws, ntxiv rau nws qhib ntau yam tshuaj lom neeg (BDO, THF, thiab lwm yam). Xa xov rau peb tam sim no kom tshawb nrhiav cov kev daws teeb meem MA uas haum rau koj txoj kev lag luam!
